Fluid transferred into the helical inflatable lumen causes the inflatable lumen to assume an expanded configuration to expand an outer diameter of the conformable conduit relative to an unexpanded configuration of the helical inflatable lumen. When in the expanded configuration and inserted in a patient, conformable walls of the conformable conduit expand outwards to contact the tracheal walls such that the conformable conduit is self-sizing to a patient's trachea size.

Abstract: Aspects of the disclosure describe a design that isolates concentrated oxygen from electrical and/or flammable components of a ventilator. In an example, ventilator components containing or otherwise interacting with concentrated oxygen are isolated from the electrical equipment and/or drained to an exterior of the housing of the ventilator, in case of a leak. For example, an isolating structure encases the concentrated oxygen-carrying components to prevent concentrated oxygen from inadvertently leaking into the inside of the housing of the ventilator. The isolating structure may be a sleeve. An isolation gas inside the isolating structure may be fluidly coupled with ambient air outside the housing of the ventilator to allow the escape of isolation gas outside of the ventilator housing.
